Date:	02/06/2017
Bugs:	#570242
ID:	201702-02

Synopsis

Multiple vulnerabilities have been found in RTMPDump, the worst of which could lead to arbitrary code execution.

Background

RTMPDump is an RTMP client intended to stream audio or video flash content

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-video/rtmpdump	< 2.4_p20161210	>= 2.4_p20161210	All supported architectures

Description

Multiple vulnerabilities have been discovered in RTMPDump.

The following is a list of vulnerabilities fixed:

Additional decode input size checks
Ignore zero-length packets
Potential integer overflow in RTMPPacket_Alloc().
Obsolete RTMPPacket_Free() call left over from original C++ to C rewrite
AMFProp_GetObject must make sure the prop is actually an object

Impact

A remote attacker could entice a user to open a specially crafted media flash file using RTMPDump. This could possibly result in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All RTMPDump users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose
      ">=media-video/rtmpdump-2.4_p20161210"
